The BQ26231PWRG4 is a multifunction, high-accuracy coulometric charge and discharge counter from Texas Instruments, ideal for portable applications with non-removable rechargeable battery packs. It operates with an intelligent host controller to provide state-of-charge information for Li-Ion, Li-Pol, NiMH, and Lead Acid batteries.
This device measures the voltage drop across a low-value series sense resistor to track charge and discharge. Key features include a single-wire HDQ communication interface, an internal temperature sensor, and low power consumption with operating current less than 80 uA and sleep current less than 10 uA. It offers high-accuracy internal timebase and resolves signals less than 12.5 uV.
The BQ26231PWRG4 is housed in an 8-lead TSSOP package, measuring 19.2 mm² with a 4.40mm width. Its compact size makes it suitable for integration into tight spaces within portable devices. The operating temperature range is -20°C to 70°C.
This component is designed for applications requiring precise battery capacity monitoring, such as portable electronics, medical devices, and other battery-powered equipment.
